Not loading creds from Shared Credentials File

[jaisrael1]

I am using Windows 10 and Windows Subsystem for Linux (WSL). In order to keep my AWS credentials centralized, I have the AWS_CONFIG_FILE and AWS_SHARED_CREDENTIALS_FILE environment variables in Windows set to the location of ~/.aws/config and ~/.aws/credentials in the Linux file system. I have also set AWS_PROFILE to the profile I would like to use.

When I run 'aws configure list' from cmd, it retrieves them just as I would expect. It gives the same output as when I run the command in the Linux subsystem except that the location of config-file is

\Users\Jake\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\rootfs\home\jaisrael.aws\config

Rather than

~/.aws/config

The keys it gets are correct. When I check AWS.config.credentials from within a nodejs script however, it comes up as 'null'. I expected it to load credentials from the config and credentials files just as the CLI does.

Hello @jaisrael1

Thanks for reporting this issue.

Is AWS_PROFILE being properly loaded in the nodejs script?

To make sure I'm understanding this fully, which command is giving you these paths?

\Users\Jake\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\rootfs\home\jaisrael.aws\config

All 3 environment variables are being properly loaded in the script.

When I type 'aws configure list' in cmd, it prints:

Name Value Type Location
---- ----- ---- --------
profile MFAProfile manual --profile
access_key [MYKEY] shared-credentials-file
secret_key [MYSECRET] shared-credentials-file
region us-east-1 config-file \Users\Jake\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\rootfs\home\jaisrael\.aws\config

So that path is the location of the config file that the region is being loaded from. It is stored in the AWS_CONFIG_FILE environment variable.

I found a workaround, I can manually set 'AWS.config.credentials = new AWS.SharedIniFileCredentials({ filename: process.env.AWS_SHARED_CREDENTIALS_FILE});'

As long as I put 'const S3 = new AWS.S3()' after the above line, everything works.

So because I can load the creds from the shared credentials file manually and everything appears to work, it looks like it's just not doing this automatically.

@jaisrael1

Have you set AWS_SDK_LOAD_CONFIG?

That needs to be set for the shared credentials file to be loaded.

See this PR for details: #1391 (comment) with additional context here: #2197 (comment)

That fixed the problem, many thanks!
